I have it, got the wood from Robert (Zitrusgaertner) in 2012. On own roots it is not enough resistant and grows rather slowly.
In 2013 I low grafted it on poncirus, it is in ground without protection since 2014, no winter damage up to now.
It comes probably from a free pollinated immature seedling of initial hybrid , since only a small number of leaves are trifoliate.
Approximately 1.5m high, but has not flowered yet.
